Modeling and analysis of the wood flexible manufacturing system based on TCPN

The timed colored Petri-net (TCP-net) model is established according to some discrete events of the Wood Flexile Manufacturing System (WFMS) using Petri-net. The model is available to not only show the machining process routes of the jobs to be processed on a flexible system, but also describe the system characteristics. At the same time, the model has been verified by witness software simulation tests, which results showed that WFMS is active without self-locking. Then to apply easy adjustment principle for this system, based on the simulation results, can raise the utilization ratio of machines.
